Loose-LEAFY HOLDER. I'

Appiicafmn vfiieii- August s, 1927. seriai No. 211,443.

This invention relates tol holders for sheets and pads, and particularlyto loose-leafY most sheet to be readily turned under 'the n pad forpossible future reference; to provide y improved supporting means forslidably and pivotally connecting the pad to the holder so as to permitthe pad Ito be 'rocked into a toene ,of the covers and positiontransverse at the same time permit the entire pad Vto move away fromsaid one cover to enable the uppermost sheet to be shifted to the bottomot the pad; to provide a holder having an improved form of back on whichthecovers are mounted; and to provide anA improved holder ot this kindwhich is particularly adapted for use in connection with lcalendar padsor memorandum pads.

An illustrative embodiment of this inven-l tion is shown intheaccompanying drawings, wherein Fig. 1 is a plan its open posi ofbrokenaway. Y f t Fig. 2 is a perspective of -the same. Fig. V3 isl anenlarged end view of the closed lholder and pad. i

Figf4 is a similar view showing theholder kopen and the pad in aposition for shifting the uppermost sheet to the bottom of the `padypartot the top cover being away and certain portions of the parts beingshown invdotteoly Outline. ,Y l

Fig. 5 is ani enlarged fragmentary view ot Athe back.-L i

of an improvedholder in Fig. '6 is a fragmentary transverse section f ofythel cover members and connectingk backv taken on thev of the holder,the view being line 646 of;Fig. 1.

In the form shown', thev holder includes a back of improvedconstruction, onwhichis mounted a pair of hinged covers, one'of, whichserves as a base tor an improved,vv

mounting adapted to support a pad of sheets or the like. Y y Y Y In thespecilic embodiment illustrated, the holder Vcomprises a back 1, towhich isl hinged a top cover 2,@and afbottom cover v3 forming#v a basefor an improved mounting 4 which is.

adapted to support a pad of sheets 5.

The back l includes two sectionsg of substantially identicalconstruction.l Each` oftion and having portions therei afpivot.l

broken l 4 for thepad of sheets comprises va binder `plate 18 adapted tosupport the pad 5, and vvhaving apertures 19, which engagera pair ot'ring ymembers 20 mountedhon the base 3 Y thesections 6 is somewhatsimilar in general construction to the cover back shown in my Patent No.1,552,437, issued September 8, 1925, In the form shown, each ofthesections 6 comprises a Ytube 7 having mounting heads 8 secured to theends thereorn by studs 9 together with a channel member arranged Withitsbaclt' againstI said tube.vr Seated in the heads 8, are U-sliapedsprings 10 arranged to connect the covers 2 and 3 with the tubes ,7 and`with `channel `members 11l of` the sections 6. The free edges of thechannel members 11 are nested together and secured by rivets 12. Thearms of the springs 10 extend inwardly into the channels 11 and similarchannels 13 forming part ot', `the coverrframes' and their innerk endsare secured against turning relative to the channel members by being`bent transversely, as shown at 14. When the lcovers 2'and 3 are open,thepspringsv 10 are under 'torsional strain, thereby tending tonormallyclose the y.holder as shownrin Fig. V3. AWith this improvedV-construction and arrangement of parts, either cover may swing witheither one of the armspof either of the springs 10 as As illustratechthecovers 2 and 3 comprise panels 15 mounted inthe channels 13 and Aframesect-ions 16.'A The edges of the panels 15 are fitted in the channelsections 13 and 16 and are secured against displacement by .rivets 17..t l

In the form shown, the improved mounting adjacent the outer edgethereof. By means y,otithe ring ymembers 20, the plate 18 is tilt- A.

ably secured to thebase 3 so Aas to -permit the -`uppermost sheetl to beshiftedl to the bottom of thevpad. In addition to its tilting movement,the lplate 18 also slides on the ring members 20-in a directionsubstantially northering members20, are slots 21 to permit the insertionof the plate 18v before thering members are attached to the c0ver'3.

'Formed on thering members 20, adjacent the. slots 21, arel shouldersj22for supporting the plate 18 Vadjacent,itsfouter edge. The plate 18 isfadapted'to be supportedv adjacent mal tothe bottom cover l3 so as topermit an i in the ring members 20, are posts which,

with the posts 24, secure the plate 18 against edgewise shifting whenthe holder is closed.

The posts 24 and ring members 2O are provided with threaded Shanks 26extending through the base 3 and provided with cushion heads 27 toprevent the cover 3 from marring the table or other supporting surface.

Secured to the binder plate 18, adjacent its inner edge, are binderringsQS for attachment to the pad of sheets 5. These rings are arrangedsoas rto permit the sheets to be transferred from one side of the plate18 to the opposite side thereof when the plate 0C* cupies apositiontransverse to the base 3, as shown in Fig. 4t.

In operation, the calendar or memorandum pad is placed on the plate 18and secured thereto by the rings 28. When the top sheet has been used,or it is desired to turn to the next sheet, the top sheet is turned overonto the open cover 2. Vhile the covers 2 and 3 are held open, theentire pad 5 is then lifted, by grasping` the krings 28, so as to causeVthe reversed sheet to drop tothe opposite 4side of the plate 18, asshown in full outline in Fig. 4. When the pad is again lowered to itsnormal position, the used sheet will be' below the plate 18, Where itmay be readily referred to -i'f needed.
